Read instructons to determine if your keyboard supports this method
Instuctions explain how to use the K-MAP and Hex Output files for making your very own custom remap of keys by modifying the cfg.ini file (cfg.ini is located in the installation directroy of your keyboard software)
The modifications are applied through the software provided by the manufacturer (check out 'how to' in instructions )
